Subject: [PATCH 00/10] Add Gigabit Ethernet driver support
Date: Fri, 1 Oct 2021 16:06:26 +0100 [thread overview]
Message-ID: <20211001150636.7500-1-biju.das.jz@bp.renesas.com> (raw)
The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are
similar to the R-Car Ethernet AVB IP.
The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller
(DMAC).
With a few changes in the driver we can support both IPs.
This patch series is in preparation for adding Gigabit ethernet driver support to RZ/G2L SoC.
The number of patches after incorporatng RFC review comments is 19.
So splitting the patches into 2 patchsets (10 + 9).
The series is the first patchset which aims to add RZ/G2L SoC with
compatible strings, E-MAC and D-MAC initialization.
Second patchset basically fillup all the stubs for the full Gigabit
Ethernet functionality.
RFC->V1:
* Added Rb tags of patch#1 and patch #9
* Renamed "rgeth" to gbeth
* Renamed the variable "no_ptp_cfg_active" with "gptp" and
"ptp_cfg_active" with "ccc_gac
* Handled NC queue only for R-Car.
* Removed RIC3 initialization from DMAC init, as it is
same as reset value.
* moved stubs function to patch#4.
* Added tsrq variable instead of multi_tsrq feature bit.
* moved CSR0 initialization from E-MAC init to later patch.
* started using ravb_modify for initializing link registers.
